[Nico Huber (Code Review)]

Hello Arthur Heymans, build bot (Jenkins),

to look at the new patch set (#2).

nb/intel/gm45: Remove UMA alignment optimization

This code path was only triggered in one corner case: GFX UMA set to
48MiB. It created a hole below UMA to save MTRRs. But, this hole was
never accounted for when calculating cbmem_top(). Instead of trying
to fix it, remove it, it's not worth the trouble.

TEST=Booted lenovo/x200 with all available CMOS gfx_uma_size settings.
